Abstract:
We present the results of an all-sky search for continuous gravitational wave
signals with frequencies in the 200-600 Hz range and frequency derivative
(spindown) from -1e-8 through 1.11e-9 Hz/s. Together with the results from [1],
this search completes the all-sky survey for frequencies between 20 to 600 Hz
on O1 data. It also demonstrates the scalability of our search on a parameter
space 26 times larger than previously considered. The results presented here
complement the LIGO O2 data results [2,3] with comparable when not better
sensitivity and do not rely on data with irregularities in the
noise-subtraction procedure. We establish strict upper limits which hold for
worst-case signal parameters and dedicated upper limits for generic ~0 spindown
signals, such as those expected from boson condensates around black holes.
